You know what you never see, though? Advice on what not to give a runner. Until now.

Click the numbers below to see the nine worst gifts for runners.

1. Shoes

“You’re a size 10, right? These are 10’s. The guy at the store said you could use them for running.”

No. No. No. No. No.

2. Cotton Socks

"Why do you hate me?" your running friend will be thinking as he or she unwraps this. "And why do you want me to develop blisters the size, and color, of cherry tomatoes?"

3.Anything With the Word “Jogger” on It

Just trust us on this one.

4. Jogging Suit

Not because of the the word jogging. Because “jogging suits,” despite their name, are not intended for actual jogging. (Or running. Or anything more athletic than lounging around the house.) Also, if you wear one you risk looking like an extra from The Sopranos.

5. Food of Any Kind Whatsoever

Is it gluten free? Organic? All natural? Vegan? Paleo-friendly? How many calories per serving? What percentage from fat? Does it have GMOs? Are you starting to see why it's a mistake to give a runner edible gifts?

6. Puppy

Sure, it’s cute now. But it will grow up, and owning an animal is a huge responsibility. Come on, people. Think ahead.
